Title: A safety device or valve, for the purpose of automatically closing gas pipes
IPC: F16K17/00
Filed: 1923-05-04
Abstract: 208,082. Duncan, W. F. May 4, 1923. Fluid-actuated valves.-A safetv cut off valve for use in gas supply systems is adapted to close when the supply is interrupted and only reopens, on restoration of the supply, when all the outlet taps have been closed. In the form shown the valve B is held from its seat against the action of a spring G by outlet pressure acting on an annular diaphragm E connected to the valve spindle by a perforated plate F. The valve member has a small leakage port D adapted to permit the building up of pressure on the outlet side when all the outlet taps have been opened and so open the valve. The leakage past the valve may be controlled by means of a self closing supplementary valve which must be opened after the supply has been restored to enable the cut-off to open. In a modification, pressure is led to a separate diaphragm chamber through a perforated hollow spindle.

Title: Improvements in and relating to storage and like equipments for vehicles
IPC: E04H6/36
Filed: 1938-04-21
Abstract: 513,923. Storing and handling motor vehicles. AUGER, H., and NICHOLSON, N. P., (Representative of PEARSON, W. E.). April 21, 1938, No. 12027. [Class 78 (iv)] In the type of apparatus in which car-carrying platforms are moved step-by-step in a closed cycle including two parallel ranks, with means for transferring vehicles laterally from rank to rank at the ends of the latter, separate platforms are used for each of the four wheels of the vehicle or for each end or side pair of wheels. Fig. 5 shows an arrangement in which separate platforms 1D, 1D<1> are used for the front and rear pairs of wheels. Each of these platforms has depending lugs 4 at the corners, one lug on each side being engaged between projections 8 on shafts 7 which are moved axially to advance the line of platforms forward one step. On the return stroke the shafts 7 are rotated so that the projections 8 are out of register with the lugs 4. The shafts 7 are moved axially by chains 10 gearing with sprockets 12 on a common driving shaft 9. Fig. 14 shows the means for rotating the shafts 7. The squared ends 14 of these shafts enter sockets 15 at the end of their stroke, the sockets being rotated by cranks 16 connected to fluid-pressure rams 18, 18' working in timed relation to the axial movement of the shafts. To transfer the platforms to the adjacent rank at the ends of the rows they are lowered first until the lugs 4 rest on wheeled transfer carriages 25, 25<1>, Fig. 6. This is accomplished by the mechanism shown in Fig. 9. Movement of the linkage 39 towards the right by hydraulic rams causes the rollers 36 to engage the cam surfaces 35 at a different point and so lower the supporting tables 21, 34, which in turn lower the platforms 1A. On reaching the other rank, the platforms are elevated again before being passed into the new rank. The transfer carriages on each side of the vehicle are connected by links 27, and each carriage has four running wheels 26, Figs. 6 and 10, and a central vertical guide wheel 26a, all engaging the H-shaped track shown. They are traversed by being connected to chains driven by sprockets 32, 32<1> on a shaft 30 driven by the motor 29. In a modification, the shafts 7, Fig. 5, are arranged outside the lugs 4 instead of inside as shown. The method of inter-connecting all the various operations for movement in timed relation also is described. Specification 502,967, is referred to in both Complete and Provisional Specifications, and Specification 502,966 in the Provisional Specification only.

Abstract: 1,137,496. Automatic volume control. NIPPON ELECTRIC CO. Ltd. 21 March, 1966 [22 March, 1965], No. 12339/66. Heading H4R. In an automatic volume control system in which the signals in the separate channels of a multichannel transmission system are compared sequentially with a single pilot signal and the result of the comparison used to control the gains of the respective channels, gaps in the signals of the channels are detected and the pilot signal input to the comparator is inhibited whenever the channel to which the comparator is switched is carrying no signal. Fig. 4 shows a system in which signals from sources 1A, 2A and 3A are fed via variable attenuators 20A, 21A and 22A, and fixed level setting attenuators 23A, 24A and 25A, to be combined in unit 27A for application to a common amplifier 28A and transmitting aerial 29A. The signal level in each channel is monitored by respective amplitude detectors 8A, 9A and 10A, the outputs from which are sequentially applied via commutating switch 16A to a comparator 18A where the level is compared with that of a pilot signal from source 7A monitored by amplitude detector 11A. An error voltage developed as a result of the comparison is applied via amplifier 19A and commutating switch 17A, operated in synchronism with 16A, to adjust the respective one of variable attenuators 20A, 21A and 22A, to bring the signal levels in all the channels to the standard level. Units 4A, 5A and 6A also monitor the signal in respective channels 1A, 2A and 3A, and if the signal is absent, e.g. due to a gap in speech or during a space in a binary digital transmission, the respective one of the switches 12A, 13A, 14A, is caused to open so that pilot signal level is not fed to the one input of the comparator while the other input of the comparator is being fed from the amplitude detector 8A, 9A or 10A, which is connected to a channel carrying no signal.
